Bacterial infection or some kind of Allergy on my foot. It started with 2 blisters on my left foot with white mucus in it. Then 2 more on right foot. My father(MD Medicine) gave me Pancef-of and Montina-L. Also using sophromicine on blisters. But now initial ones are getting dried and skin becomes black there. But now some new arising on my hand.I never had any blister on my upper body. I never had such a problem. I am a 24 year , male, student living in hostel. So might have contacted from some friend. Photos also attached with the question. Please reply asap.Thank you.
